DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

In FIGS. 1 to 3 , a composed element 1 according to the invention isrepresented, in this case in the form of a piece of furniture, moreparticularly a cupboard. The element 1 comprises a rear wall 2, as wellas a number of constructional parts, which in this case are indicatedgenerally by reference number 3 and which form a whole in which the rearwall 2 is provided, in such a manner that the rear wall 2 forms the rearside of the composed element 1.

In the example, the constructional parts 3 are formed by a bottom wall4, a left-hand side wall 5, a right-hand side wall 6, a top wall 7 and ashelf 8. In this example, the rear wall 2 is composed of two rear wallparts 9 and 10 situated one above the other.

As can be seen in FIG. 2 , this preferably relates to a composed element1 of the type of which the constructional parts forming the actual basiccarcass, in this case the aforementioned walls 4, 5, 6 and 7,substantially can be locked to each other exclusively by means ofcoupling parts 11-12 integrated at the edges, thus, without thenecessity of separate connection elements. More particularly, it is alsopreferred that, as represented, the constructional parts 3 preferablyall consist of flat or relatively flat elements, as a result of whichthe whole can be marketed as flat-pack furniture.

The coupling parts 11-12 may be of any form, however, as represented,preferably consist of a tongue 13 and groove 14 which are provided withlocking parts 15-16 engaging behind each other. Examples hereof arewidely known, amongst others, from the international patent applicationWO2010/070605.

Further, the composed element 1 is at least provided with seats 17 and18, and in the example also 19 and 20, in which the rear wall parts 9-10are taken up, which seats, in the example, consist of grooves 21-22 onopposite sides of the basic carcass, thus, in the inner sides of theside walls 5 and 6, as well as grooves 23-24 on the inner sides of thebottom wall 4 and the top wall 7. Herein, this relates to grooves whichare integrated in the respective walls 4-5-6-7, which will become clearfurther below.

As represented in FIGS. 4 to 7 , the grooves comprise a first side wall25, which borders such groove towards the front side of the piece offurniture, a second side wall 26, which borders such groove towards therear side of the piece of furniture, and a bottom 27. The side wall 26is part of an edge 28 behind which the respective rear wall parts thusare retained in mounted condition.

In the represented example, each groove as such is formed by a recess 29in the respective constructional part, whereas the edge 28 is formed bya portion 30 of a relatively stiff finishing tape 31, which is providedon the narrow side 32 of the respective constructional part and wherebysaid portion 30 reaches up to in front of the recess 29. However, it isclear that the first aspect of the invention is not restricted to themanner how such groove and the edge bordering the groove are composedmaterially, and that said groove and edge, within the scope of thisherein below explained first aspect, can also be realized in any othermanner.

In accordance with the first aspect of the invention, at least the seats17-18 are configured such that said rear wall parts 9-10 can be slidinto the seats 17-18 starting from the rear side of the composedelement, more particularly from a position which differs from the finalplane in which the rear wall parts 9-10 are situated in the finalcondition. More particularly, the whole is configured such that, whenall constructional parts to which the rear wall 2 has to be attached aremounted to each other, the rear wall 2 still, as aforementioned, can beslid into the seats 17-18 and consequently also can be positioned in theseats 19-20.

To this aim, as represented in FIG. 3 , two passages 33-34 are presentbetween the grooves 21-22 and the rear side of the composed element 1,which allow that the rear wall parts 9-10 can be slid up into thegrooves starting from the rear side, through said passages 33-34,possibly with a certain bending and/or other deformations in therespective rear wall parts and/or the respective edges. In the example,the passages 33-34 are situated on opposite sides of the rear side ofthe piece of furniture, such approximately halfway up. As can be seenmore specifically in FIG. 4 , such passage 33-34 consists in that theedge 38 locally is not present over a restricted distance, or accordingto an alternative at least is more pronouncedly less present, in thiscase in that the finishing tape 31 locally is cut away.

As can be seen in FIG. 3 , the passages are situated at the height ofthe location where the rear wall parts 9-10 merge into each other, thus,at the height where the upper edge 35 of the lower rear wall part 9 andthe lower edge 36 of the upper rear wall part 10 adjoin against eachother or approximately against each other.

It is clear that the grooves 23 and 24 form seats for the lower edge ofthe rear wall part 9 and the upper edge 38 of the rear wall part 10. Allthis permits that the rear wall parts at a first pair of opposite edges,namely the edges 39-40 and 41-42, are displaceable in said grooves21-22, until they also at a second pair of opposite edges, in this caseformed by the lower edge 37 of the lowermost panel and the upper edge 38of the uppermost panel, are positioned in the grooves 23-24 presentthere.

In the represented example, the whole is configured such that the tworear wall parts 9-10, starting from the passages 33-34, can be slid inopposite directions D1 and D2 into the respective grooves 21-22, morespecifically as explained herein below by means of FIG. 5 . It is clearthat herein first the furniture carcass is composed, as illustrated inFIG. 2 . Subsequently, the lowermost rear wall part 9 is slid accordingto direction D1 through the passages 33-34 towards the bottom side ofthe piece of furniture into the groove, thus, starting from an inclinedand mostly somewhat bent position P1 towards a final position P2 in thefinal plane of the rear wall. In the position P2, the lowermost rearwall part becomes seated with its lowermost edge 37 in the lowermostgroove 23. Subsequently, the uppermost rear wall part 10, starting froman inclined and mostly somewhat bent position P3, is slid, via the samepassages 33-34, according to the represented direction D2 into thegrooves until it finally also assumes a position P4 in the actual planeof the rear wall. It is noted that the dimensions of the rear wall partspreferably are such that, when the latter are situated against eachother in the aforementioned positions P2 and P4, they still are seatedwith the lower edge 37 and upper edge 38, respectively, in the grooves23 and 24.

For illustration's sake, FIGS. 6 and 7 also represent cross-sections inmounted condition.

In FIG. 8 , a variant is represented, wherein the rear wall part is madethinner towards one edge, in this case by means of a chamfer 43. Asrepresented, this facilitates bringing such rear wall part initiallybehind the edges of the respective grooves.

The composed element 1 represented in FIG. 3 is also provided with anattachment piece 44 for the rear wall parts 9-10, which, in accordancewith the third aspect of the invention, cooperates with an intermediatepanel, in this case the shelf 8. The composition of the representedembodiment hereof, as well as the working thereof, is explainedhereafter with reference to FIGS. 2 and 9 .

In view of said cooperation, the attachment piece 44 is provided with anattachment portion 45, which engages on the rearward-directed side 46 ofthe shelf. This attachment portion 45 is performed as a clamping partwhich can be pressed down in an opening 47, such as a groove, which isprovided in the respective shelf 8 for this purpose, more particularly aclamping part with barbs 48.

Further, the attachment piece 44 comprises a stop-forming part 49, inthis case in the form of a flange which, in the mounted condition,cooperates with the rear sides of the rear wall parts 9-10. Theattachment portion 45 and the flange form a substantially T-shaped body,wherein the flange defines two wings 50-51 situated on opposite sides ofthe attachment portion.

Further, the attachment piece 44 comprises a support portion 52laterally cooperating with the adjoining edges of the rear wall parts.Herein, the support portion 52 is performed as a tensioning part whichpushes the respective rear wall parts away from the attachment piece 44,preferably such that they are pressed down in their seats. Thetensioning part is formed by elastically deformable lips 53-54 acting onthe rear wall parts with an elastic force.

As represented in FIG. 2 , the attachment piece 44 may be performed inthe form of a profile strip, for example, of synthetic material.

In the example of FIG. 9 , the wings 50-51 comprise elastically bendableparts 55-56, which, in the mounted condition, exert a permanent pressingforce. On the one hand, this offers the advantage that the rear wallparts are permanently pressed against the rear side of the shelf 8. Bythis pressing force, a clamping is obtained, too, which effects that itbecomes more difficult for the rear wall parts 9-10 and the shelf 8 tomove in mutual respect, by which the composed element becomes lesssensitive to possible wobbling movements which might arise in such pieceof furniture as a result of play.

In FIG. 10 , a variant of the attachment piece 44 is represented,wherein the flange is substantially flat. FIG. 10 also clearly showsthat the attachment piece is made as a profile strip.

It is noted that such attachment piece 44, and in particular when it ismade as a profile, can consist of any suitable material, for example, ofmetal or synthetic material, wherein synthetic material, due to itselasticity, is preferred.

Possibly, such attachment piece 44 and at least one of the rear wallparts 9-10, and preferably both, may comprise locking parts whichcounteract a mutual lateral displacement, mutually among the two rearwall parts, and/or mutually among one or more rear wall parts and apartition wall. In FIG. 10 , as an example, such locking parts 57-58 arerepresented in dashed line as an alternative. Herein, they consist oflocal protrusions, which are intended for cooperation withnon-represented openings in both rear wall parts.

The attachment pieces 44 preferably are performed such that they can beprovided manually in a simple manner, preferably without tools. In therepresented example, providing such attachment piece 44 thus also isperformed simply by positioning it between the two rear wall parts 9-10and pressing it down in the opening provided for this purpose. Theattachment portion 45 then provides for that the attachment piece isfixedly retained in the shelf 8. The stop-forming part 49, or, thus, thewings 50-51, provide for that the rear wall parts remain positionedagainst the shelf. The support portion 52 supports the rear wall partson each other, wherein between these rear wall parts also a tensioningforce is exerted by the portions 55-56.

It is noted that, as can be seen in FIG. 3 , at the location where suchattachment piece 44 has to be provided, recesses 59 can be provided inone or both of the rear wall parts 9-10. These recesses 59 offer variousadvantages. A first advantage consists in that, when the rear wall parts9-10 rest freely upon each other, it is directly visible where theattachment piece 44 has to be provided. A second advantage is that theinstalling person does not need to first push the two rear wall partsout of each other in order to install the attachment piece 44. A thirdadvantage is that the two rear wall parts, as long as such attachmentpiece is not applied next to the recesses 59, rest upon each other andthe upper rear wall part remains present in the respective groove withits upper edge, by which is excluded that, while applying the attachmentpiece, one would have to pay attention to whether the uppermost rearwall part slides into the pertaining groove.

The recesses 59 can be exclusively present there where the attachmentpieces 44 are provided, however, as represented in dashed line in FIG. 3, they can also be present on other locations, more particularly onrespectively two opposite edges of such rear wall part, such that,irrespective of how the installing person provides the rear wall parts,these latter will always be in the right position for still providingthe attachment piece.

In FIGS. 11 and 12 , a variant of such attachment piece 44 isrepresented. The attachment portion 45 is designed as a screw part,which can be screwed down in an opening 60 which for this purpose hasbeen provided in the shelf 8 concerned, either directly in the materialof the shelf or, as represented, in a bush 61, provided with screwthread and being fixed in the opening 60 for this purpose.

Here, too, the attachment piece 44 comprises a stop-forming part 49, inthis case in the form of a round flange which, in the mounted condition,cooperates with the rear sides of the rear wall parts 9-10. The flangecomprises a portion 62 in the form of a turning knob, as well as aconical or inclined portion 63, the inclined side 64 of which, when theattachment piece is screwed down, comes into contact with the edges ofthe rear wall parts. As a consequence of said cooperation, not only aclamping down of the rear wall parts against the shelf 8 is obtained,but also a lateral pushing-apart of the rear wall parts is obtained, bywhich the play thereof in the seats is reduced or even removed and atension is created, by which the rigidity of the piece of furniture isenhanced. The turning knob possibly may be screwed down so far that theaforementioned portion 62 is tensioned with its rear side against therear wall parts, whereas the portion 63 penetrates somewhat into thematerial of the rear wall parts. It is clear that the portion 63 hereinfunctions both as a support portion 52 and as a tensioning part.

Herein, the recesses 59 preferably are realized locally, for example, inthe form of approximately semi-circular recesses, whereby they alsoautomatically function as laterally-effecting locking parts, wherein amutual lateral displacement of the rear wall parts is excluded.

In FIGS. 13 to 15 , another variant is represented. Here, too, a bush65, provided with screw thread, is attached in the rear edge of a shelf8 or the like. Into this, an attachment piece 44 is screwed, which fitsinto the bush 65 with an attachment piece 45 which is provided withscrew thread. The attachment piece 44 comprises a stop-forming part 49in the form of a flange, with a foldout-handle 66 for rotating andtensioning the whole, as well as a support portion 52, functioning as atensioning part, with a radial surface 67, wherein the distance of thelatter to the central axis of the attachment portion varies in functionof the circumference, preferably in that the support portion iselliptical. Also, pawl-shaped teeth 68-69 are provided on the bush 65and the attachment piece 44, which, possibly by deformation in onemutual direction, in fact can be rotated in mutual respect, however, areprevented from rotating back. During assembly, when the attachment piece44 is screwed into the bush 65, a condition is created wherein theelliptical support portion 62 is tensioned between the edges of the tworear wall parts and thus pushed the latter apart. It is clear that therecesses 59, the shape of the support portion 52 and more particularlythe contour of the surface 67 thereof, and the screw threads in the bush65 and on the attachment portion 45, are adapted such in a fittingmanner that the support portion initially gets with its smallest radialdimension between the rear wall parts and, when rotated from thisposition, provides for the intended tensioning action.

It is clear that the invention is not restricted to composed elements 1of which the rear wall is composed of two rear wall parts, or whereinthe passages 33-34 are situated halfway of the height of the composedelement. In order to demonstrate this, hereafter, by means of FIGS. 16to 26 , some variants of composed elements 1 are described, wherein therear walls are realized in a different manner.

In FIG. 16 , in a rear view a composed element 1 is represented havingonly one rear wall part 70. Seats 17-18-19-20 in the form of grooves arelocated on all four sides. Next to the lower edge, on opposite sidespassages 33-34 are provided for providing the rear wall part 70. Asrepresented in detail in FIG. 17 , such passage 34, in a mannercomparable to that of FIG. 4 , can consist of a cutout in the finishingtape 31. Applying the rear wall part then is performed, in accordancewith the first and second aspect of the invention, by sliding the rearwall part through the passages 33-34 into the grooves, according toarrow D3 in FIG. 18 , in order to subsequently letting it drop somewhataccording to arrow D4 in order to obtain that it becomes seated in theseats on all edges, as illustrated in FIG. 19 .

In FIGS. 20 to 24 , a variant is represented wherein use is made of tworear wall parts 9-10, which each as such are made multi-part, thus, inthe form of a folding back, respectively. Each rear wall part 9, 10,respectively, comprises two portions 71-72, which respectively arelinked together by means of a hinge portion 73. FIG. 22 shows such rearwall part in partially folded-open form. Herein, the hinge portion 73 isformed by a glue joint which connects the two portions and functions asa kind of film hinge. FIGS. 23 and 24 represent a magnification at theheight of the hinge portion 73, in a completely folded-open conditionand a completely folded-tight condition, respectively. It is clear thatsuch rear wall part in the folded-tight condition has only half the sizeas in folded-open condition. Such rear wall part, which is performed asa folding rear wall, offers the advantage that in mounted condition, itwill behave as a single part, which renders a better rigidity to thepiece of furniture than two separate parts. At the same time, theadvantage is offered that such rear wall part in the folded-tightcondition is easier to package and transport, which is very useful withflat-pack furniture.

The two rear wall parts 9 and 10, after having been folded open, areslid through the passages 33-34 into the respective seats in a manneranalogous to that of the embodiment of FIG. 2 .

The whole preferably is constructed such that all transitions, thus, thetransitions between two rear wall parts as well as the transitionsbetween the portions 71-72, will be situated behind shelves or the like.An attachment piece 44 can be provided between the two rear wall parts 9and 10. Possibly, also additional attachment pieces 74, analogous to theattachment pieces 44, can be provided at the folding edges.

It is noted that the hinge portion can also be realized in othermanners. For example, a covering film, which is provided continuouslyover two or more portions of a rear wall part, can be applied as a filmhinge at the location of the transitions.

It is also noted that the rear wall parts and attachment pieces do notnecessarily have to be directed horizontally. For example, FIGS. 25 and26 , in a rear view, represent an embodiment of a piece of furniturewith vertically-directed rear wall parts 75-76 and attachment pieces 44.These latter then cooperate with openings in a partition wall 77. It isclear that providing the rear wall parts then is performed by means ofpassages 33-34, which are situated on the top and bottom of the piece offurniture.

Generally, the constructional parts 3 and rear wall parts can consist ofvarious materials, however, preferably use shall be made of coveredboard material. This is especially recommended for the manufacture offlat-pack furniture.

The constructional parts 3 preferably consist of a basic board 78, whichis provided with a covering 79 on opposite sides.

Such basic board 78 preferably is based on vegetable matter and moreparticularly consists of particles and/or fibers consolidated by meansof a binding agent, whether or not mixed with other materials. Woodmaterial is most recommended, preferably in the form of chips and/orfibers, for example, particle board or MDF/HDF, possibly at leastpartially and possibly entirely of recycled wood.

Possibly, more light-weight basic boards can be applied by making use offlax chips or by mixing in cork, expanded synthetic material parts orthe like. It is also not excluded to apply hollow boards for the basicboard 78, which, however, have strips at the edges in which therespective seats are provided. The hollow portions can be provided withhoneycomb structures.

The basic board 78 can have any thickness. Usual thicknesses forfurniture are situated between 12 and 30 mm, however, other values arenot excluded.

Said covering 79 preferably is formed by laminate, for example, in theform of DPL, however, other coverings are not excluded, such as lacquer,films, veneer and the like.

The basic board 80 of the rear wall and the covering 81 thereof can beconstructed in a similar manner. Preferably, the back, however, isrelatively thin and has a thickness in the order of magnitude of 3 mm.Preferably, as represented, it is provided with a covering 81 on oneside only. In a practical embodiment, to this aim a MDF or HDF board isapplied and the covering consists of a film. Other possibilities are notexcluded.

It is clear that the combination of the fourth aspect of the inventionwith the first aspect offers a practical solution for realizing theaforementioned passages 33-34, as in that case only the finishing tape31 has to be interrupted locally, which can be realized very easily bymeans of a movable cutting tool, such as a milling cutter, which can bepresent in the tape adhering device. In the actual furniture panel,exclusively a straight-lined recess 29 has to be realized, and thenecessity of particular milling treatments in the furniture panelitself, for forming passages, is excluded.

The herein above-described embodiment of the fourth aspect can also berealized independent from the first aspect. In fact, it is clear thatsaid fourth aspect in general relates to the manner in which the seatfor the rear wall is formed, wherein this is independent from the mannerin which the rear wall is provided in the pertaining seats. As anexample, in FIGS. 27 and 28 thus a composed element 1 is represented,more particularly a piece of furniture, in which no passages, asaforementioned, are present; however, the rear wall part 82 is let downinto the seats in the usual manner between the two side walls 5-6 andwherein then only thereafter the upper wall 7 is provided on the sidewalls, wherein the attachment of the rear wall part, however, isperformed by applying the fourth aspect of the invention.

In FIGS. 29, 30 and 31 , in cross-sections similar to that of FIG. 28 ,a number of particular embodiments of the fourth aspect are represented.The particularity herein consists in that the finishing tapes 31, atleast at one pair of opposite sides of the rear wall part 82, areprovided with hook-shaped locking parts 83, which cooperate with therear wall part, more particularly with groove-shaped recesses 84 in therear wall part. In this manner, it is obtained that the rear wallcontributes better to the rigidity of a piece of furniture, by which thelatter will wobble less than in the case that no hook-shaped lockingparts are applied.

Preferably, the finishing tapes 31 are already provided with thehook-shaped locking part before they are applied.

In the embodiment of FIG. 29 , the finishing tape 31 has a hook-shapedlocking part 83 in that, at a distance from the edge of the finishingtape, a recess 85 is formed in the finishing tape. FIG. 30 represents avariant, wherein the hook-shaped locking part protrudes from the actualplane of the tape.

In the embodiment of FIG. 31 , chamfers 86 are formed on the protrudinglocking part. This is, for example, useful when such rear wall part hasto be slid into the seats according to directions D5-D6. This may be,for example, when it is intended that the rear wall part is somewhatelastically bent in order to be subsequently positioned between the sidewalls of the piece of furniture, such that, after releasing it, it willrelax in a flat condition, with the edges in the seats. As an example,the embodiment of FIG. 31 can also be useful for being applied on thebottom and top in an embodiment of a piece of furniture according toFIG. 27 .

FIGS. 32 and 33 represent a particular embodiment of the fourth aspect,with the particularity that the whole is configured such that a rearwall part 82 can be provided at its place by means of a frontal movementM and by bending the finishing tape 31. Preferably, this issubstantially realized by applying a material removal at the rear sideof the respective rear wall part, which in the represented exampleconsists of a chamfer 87.

The present invention also aims at a device for attaching a shelf bymeans of a shelf support, wherein the whole is designed such that, onthe one hand, the shelf support in mounted condition is of little or nohindrance, and, on the other hand, the provisions which have to be madeon the shelf itself can be realized in a simple manner in respect toproduction techniques and at low costs.

According to the invention, to this aim a device is applied which ischaracterized in that the bottom side of the shelf, starting from thelateral edge thereof, is provided with a recess; that, starting fromthis recess, an upward-directed bore hole extends in the shelf; that alateral bore hole is present in the side wall; that the shelf supportcomprises a body which fits into said recess and, in the mountedcondition, is sitting at least partially and preferably completelycountersunk in respect to the bottom side of the shelf; that anupward-directed protrusion fitting in said bore hole is present on saidbody; and that the shelf support further comprises an attachment partwith which it fits into the lateral bore hole.

According to a first preferred embodiment, herein it is striven for thatthe provisions which have to be realized on the shelf consistexclusively of a milled-in part or the like and further one or more boreholes. A practical example thereof is represented in FIGS. 34 and 35 ,in which FIG. 34 represents the shelf support 88 as such in perspectiveand FIG. 35 represents a cross-section in mounted condition. Asaforementioned, the shelf support 88 comprises a body 89 which fits intoa recess 90 and is countersunk in respect to the bottom side 91 of theshelf 8. On this body 89, an upward-directed protrusion 92 is present,which fits into a bore hole 93. Further, the shelf support 88 comprisesan attachment part 94 with which it fits into a lateral bore hole 95 ina side wall. This attachment part 94 is indirectly in connection withthe body 89 via an upward portion 96 fitting into an opening formed byhalf a bore hole 97. Further, the attachment part 94 can be providedwith clamping ribs 98.

As schematically indicated in FIG. 35 , the recess 90 can be formed bymeans of a laterally moving finger cutter 99, whereas the bore holes 93and 97 can be realized simply by means of drills 100-101.

According to a second, more preferred embodiment, all provisions to beapplied at the shelf are realized exclusively by means of bore holes,wherein a first bore hole then offers a seat for the actual body of theshelf support, whereas the second bore hole offers room for an upwardlydirected protrusion. A practical example thereof is represented in FIGS.36 to 38 . FIG. 36 represents the shelf support 88, FIG. 37 representsthe bottom side of the shelf 8, and FIG. 38 represents a cross-sectionthereof. As represented, two bore holes 102-103 of different diameterare provided in the bottom side of the shelf 8. The shelf support 88comprises a body 89 which fits into the largest bore hole 102, and anupwardly directed protrusion 92, which, in the mounted condition, isintended for engaging in the smaller bore hole 103. Further, a laterallydirected attachment part 94 is provided on the body 89.

FIGS. 39 to 45 represent an example of the fifth aspect of theinvention. The particularity herein consists in that the composedelement 1 is provided with attachment parts 104, which are made in onepiece with one or more of the constructional parts and behind which therear wall 2, usually with a certain deformation, for example, bending,can be pressed down. As represented, these attachment parts 104preferably consist of cam-shaped portions which border the seat for therear wall and which preferably have a somewhat inclined guiding side 105and a steeper locking side 106. As represented, the use of thesecam-shaped portions further can be combined with a seat 17-18-19-20 inthe form of a groove. FIGS. 40 to 42 , at a larger scale, representviews in the mounted condition. FIGS. 43 to 45 schematically illustratethe manner in which the assembly of the rear wall 2 is performed, to witsimply by pressing the rear wall over the cam-shaped portions.

As can be seen in the magnified views of FIGS. 41 and 42 , for the seatspossibly use can be made of grooves having a particular design, suchthat the rear wall part, as it is getting situated deeper in the groove,becomes less free and even will become clamped. In this case, this isachieved in that the respective groove, in cross-section, is inclined inrespect to the plane of the rear wall.

It is noted that the use of such attachment parts can be applied on one,two opposite, three or all four sides of a piece of furniture as well.If it is applied on all four sides, then possibly particular provisionscan be made in order to obtain that the rear wall, or the component rearwall parts thereof, can deform in a smooth manner and can be pushed onall edges to behind the cam-shaped portions. This is possible, forexample, by providing the rear wall part, next to the corner points,with cut-out portions 107, as depicted in FIG. 46 .

FIGS. 47 and 48 represent a variant of such attachment part 104, in theform of a cam-shaped part, the surface of which gradually merges intothe surrounding material. This portion can be formed in a simple mannerby subjecting the milling cutter, by which the edge zone is formed, to atilting movement.

FIG. 49 schematically represents another composed element 1 according tothe invention, which has the characteristic that the rear wall can alsobe provided at its place after assembly of the other parts. Theparticularity herein consists in that the rear wall 2, or certain rearwall parts thereof, can be slid into seats 17-18 starting from the outerside of the piece of furniture, wherein blocking means are providedwhich in fact allow to provide the rear wall, but which prevent that therear wall can slide out of the seats by itself. These blocking meanspreferably consist of one or more stops, in the example one stop 108,along which the rear wall cannot move without any deformation. Suchstops preferably are realized at the piece of furniture in one piece.

In FIG. 49 , in dashed line another alternative is depicted, withpassages 33-34 giving out towards the rear, along which the rear edgealso can be brought into the seats 17-18, by means of a forced bending.Once the rear wall is provided in the seats 17-18 via the passages33-34, it remains upright by itself and is maintained in its place bythe stop 108. It is clear that the composed element 1 from FIG. 49 insuch case also represents an example of the first aspect.

It is clear that all above-described rear wall constructions accordingto the invention primarily are intended for being applied with composedelements with constructional parts which can be locked together at leastat the corners by means of profiles. It is precisely with suchembodiments that one strives for working with a minimum of small looseaccessories or even without these accessories, which is preciselyfulfilled by the embodiments described herein above. In other words, theinvention shows its advantages best with so-called “click furniture”.Thus, the herein above-described examples, when applied with such “clickfurniture”, automatically form examples of the sixth aspect of theinvention.

However, the above does not exclude that such rear wall constructionsare applied in other furniture, too. The herein above-described rearwall constructions as such will remain offering advantages even then.

Finally, in FIGS. 50 and 51 a practical embodiment of the seventh aspectis represented. This seventh aspect provides for a corner connection109, which, in the mounted condition, provides additional rigidity tothe whole. The particularity herein consists in that a tongue and groovecoupling with locking parts 15-16 is applied, wherein said locking partsare situated substantially on one side of the tongue only, whereinportions positioned opposite to each other are present on both sides ofthe tongue, namely first portions 110-111 on the side where the lockingparts are situated, and second portions 112-113 on the other side, withthe characteristic that, when the second portions 112-113 theoreticallyare positioned against each other, there is a small distance A betweenthe first portions 110-111. In FIG. 50 , this means that, when thecoupling parts theoretically are positioned opposite each other at adistance from each other, there is a distance B between the portions112-113, whereas then there is a distance B+A between the portions110-111. Herein, the intended distance A is less than 1 mm andpreferably more than 0.1 mm. Practically, it will be 0.2 to 0.6 mm, andthe best results are obtained with nominal values of 0.3 to 0.5 mm, with0.4 mm as a best value.

Preferably, all this is combined with the use of a so-called pretension,obtained by a small theoretical overlapping of the profile shapes, whichprovides for creating a tension T. By maintaining said distance A in thetheoretical form, unexpectedly it was found that a particularly rigidcorner connection can be achieved, in particular when this principle isapplied at two successive corner connections of the composed element,wherein the distances A at these successive corners do not necessarilyhave to be equal to each other.

It is noted that the plane of the portion 113 does not necessarily haveto be situated in the extension of the plane of the portion 111. Asrepresented as a variant in dashed line in FIG. 50 , this may also besituated displaced, wherein thus also the portion 112 must be displacedover the same distance, such that the same distance B remains applied.

Further, this has proven particularly useful with coupling parts 11-12wherein use is made of a split tongue, thus, with the represented gap114.

When this aspect then is combined even further with the third aspect ofthe invention, a wobbling of the piece of furniture is counteracted ontwo fronts, which results in that finally a very rigid and stable pieceof furniture is obtained.

It is noted that according to the invention, by a “composed element” anelement has to be understood in “composed” as well as in “still to becomposed” condition. Thus, this, for example, also means that a not yetassembled and still packaged flat-pack piece of furniture, which, in themounted condition, shows one or more of the characteristics of theinvention, has to be considered a “composed element” already.

The present invention is in no way limited to the embodiments describedby way of example and represented in the figures, on the contrary, suchcomposed elements, and more particularly the parts thereof which areused for realizing the aforementioned aspects, in particular the hereinabove-described rear wall constructions, may be realized according tovarious variants without leaving the scope of the invention.

It is clear that the invention in general also relates to rear wallconstructions as described herein above, more particularly to theattachment of the rear wall parts, irrespective whether this is intendedfor flat-pack furniture or not.

In FIGS. 52 and 53 , two other variants are represented of attachmentpieces 44 which can be applied in a similar manner as in FIG. 9 . Theseattachment pieces 44 substantially consist of an attachment part 45 anda stop-forming part 49. Moreover, they preferably also comprise supportportions 52, which are intended for cooperating with the rear wall parts9-10. The attachment parts 45 preferably are provided with barbs,clamping ribs or the like, indicated by reference 48.

A particular independent characteristic of the embodiments from FIGS. 52and 53 consists in that the attachment piece 44 is provided with one ormore anti-slip parts 115, which provide for that an increased frictionis present between the clamped attachment piece and the rear wall parts9 and/or 10. These anti-slip parts thus preferably are situated at thebottom sides of the wings 50 and 51, and possibly also at the supportportions 52.

In a preferred embodiment, the anti-slip parts 115 to this aim areformed of a material 116 which is softer than the material 117 of whichthe actual body of the attachment piece 44 is formed. Preferably, forthe materials 116 and 117 synthetic materials, preferably rubbers, areapplied, having a different hardness. Herein, it is preferred that thematerial 116 has a shore hardness of less than 50 and still better ofless than 30, for example in the order of magnitude of 25, whereas thematerial 117 has a shore hardness of more than 50, for example, 75,however, preferably less than 100. Thereby, the strip-shaped attachmentpiece 44 will remain somewhat supple in its totality, such that it canbe pressed on systematically in its place by an unwinding movement. Thisalso offers the advantage that, if desired, the attachment piece 44 canbe relatively long and may even extend over the entire or almost entirelength of the adjoining rear wall part.

According to a variant, for the anti-slip parts also adhesive means, forexample, adhesive strips, can be applied, whether or not in combinationwith a more supple material 116.

Another independent characteristic, which either can or cannot becombined with the aforementioned characteristics, consists in that theattachment piece consists of two or more co-extruded materials, in thiscase 115 and 116, which impart various features to the attachment piece.In this manner, the material choice can be optimized in function of thefeatures which are to be imparted to the attachment piece at certainlocations.

As represented in FIG. 53 , the wings 50 and 51 can be directed somewhatdownward, such that, after being pressed on, they exert a lastingelastic force.

According to still another independent aspect, the invention relates toan attachment system 118 for attaching component parts to each other, inparticular for providing furniture accessories on furniture parts, andsuch in a simple manner, preferably without necessitating tools. Moreparticularly, this relates to an attachment system which is particularlysuitable for attaching handles and the like onto furniture parts. By wayof example, in FIGS. 54 to 57 a handle 119 is represented which is fixedon a drawer front 120 by means of such attachment systems 118.

According to the invention, such attachment system 118 substantially ischaracterized in that it consists of a body 121, which might also becharacterized as a holder or a connection piece, which on one extremityis provided with a first connection part 122 intended for cooperatingwith an accessory, in the example thus the handle 119, and on a secondextremity is provided with a second connection part 123 which cancooperate with an attachment element 124. According to a preferredembodiment, the attachment system 118 shows one or more of the followingcharacteristics, which can be applied in any combination with theaforementioned basic characteristic:

-   -   The body 121 comprises a design by which it fits into a bore        hole 125, preferably in that it comprises parts 126 defining a        cylindrical outer surface 127;    -   The first connection part 122 consists of internal or external        screw thread, and preferably, as represented, of a protruding        screw thread portion 128 with external screw thread 129, which        can be screwed into a bore hole 130 in the accessory;    -   The second connection part 123 consists of a clamping or        snapping portion on which or in which the attachment element 124        can be pressed down;    -   The attachment element 124 is made as a press-on plug or a screw        plug which can cooperate with the second connection part 123 and        thus simply can be pressed down thereon or therein;    -   The second connection part 123 and the attachment element 124        cooperate via toothed parts or barbs 131-132, which latter        preferably are situated on segments 133-134 and 135-136 provided        diagonally opposite each other.

In the represented example, all these characteristics are combined.

The functioning of the attachment system 118 can simply be deduced fromthe figures. The body 121 is provided with the first connection part 122on the accessory, in this case by screwing it down with the screw threadpart 128 into the bore hole 130. Then, the accessory is provided withthe body 121 in the bore hole 125, after which, from the other side, theattachment element 124 is provided on the second connection part 123, inthis case by pressing down the respective attachment part 124 with thesegments 135-136 between the segments 133-134.

It is noted that the toothed parts 131-132 possibly can be made as screwthread, such that the attachment element 124 can be pressed down in asimple manner, however, still can be unscrewed by means of a screwmovement. The toothed parts then cannot be provided on such segments andthen have to be present on concentric parts instead.

The component parts, in particular the body 121 and the attachmentelement 124, can consist of any material, however, preferably are formedof synthetic material, for example, PVC.

FIGS. 58 and 59 illustrate still another attachment system 137 accordingto the invention for providing an accessory, such as in this case asmall handle or pulling handle, on a furniture part 139.

The attachment system 137 is characterized in that it substantiallyconsists of a connection piece 140 with two screw thread portions 141and 142, whereby the first screw thread portion 141 is suited for beingattached to an accessory 138, and the second screw thread portion 142 ismade as a screw and thus can be screwed down in the furniture part 139in a self-tapping manner, possibly in a bore hole 143 provided therein.

Preferably the first screw thread portion 141 is made with metricthread. This screw thread portion 141 preferably is realized as aportion with external screw thread which can cooperate with internalscrew thread 144.

The second screw thread portion 142 preferably is provided withso-called wood thread, thus, screw thread for screwing into wood, asalso applied in so-called Euro screws.

Further, the whole is designed such that the accessory can be screwedonto the connection piece only up to a certain length, which can beobtained, for example, by means of the represented stop-forming edge145.

The functioning can simply be deduced from the figures. The accessory138 is screwed down on the screw thread portion 141, after which thewhole is screwed into the bore hole 143.

The connection piece 140 preferably consists of steel; however, othermaterials are not excluded.

FIGS. 60 to 63 represent another variant of a shelf support 88. Thislatter comprises a body 89, which can cooperate with a bore hole in thelower side of a shelf, and further a collar or flange 146, which isintended for being situated against the lower side of the shelf. Thebody 89 substantially is round, however, in fact preferably shows aflattened part 147, which is intended for coinciding with the side ofthe shelf. The attachment part 94 comprises clamping ribs 98.

An important independent major characteristic which is present in therepresented shelf supports is that the attachment parts 94 as well asthe tab-shaped bodies 89 in mounted condition are situated between theplanes determined by the upper side and the lower side of the shelf,such with the possible exception of a collar or flange 146 or the like.

FIGS. 64 to 67 represent an embodiment with a body 89 which is madeslimmer than in FIGS. 60 to 63 .

FIGS. 68 to 70 represent an attachment system 148 for a slide 149 for adrawer, as well as an attachment element 150 applied therewith, whichallows smooth assembly.

The slide 149 consists of at least two parts, namely at least one fixedpart 151, which is intended for being attached to a cupboard wall 152 orthe like, and at least one movable part 153 to which the drawer will beattached.

The attachment system 148 is particular in that it shows one or more ofthe following features, which in the represented example all arecombined, however, also may be present as such or in any reducedcombination:

-   -   The attachment system 148 makes use of one or more clamping        plugs 154 which fit through openings 155 in the fixed part 151        and which can be pressed down in bore holes 156;    -   The one or more aforementioned clamping plugs 154 can be        pre-mounted in the openings 155 and comprise retention means by        which they are retained in the openings, which in the example is        obtained in that the clamping ribs 157 on the one hand and a        portion 158 on the other hand are acting in both directions as        stops around the openings 155;    -   The attachment element 150 comprises at least two clamping plugs        154 which are connected by a common basis 159, which has the        advantage that such element 150 can be mounted in only one        position or only a limited number of positions in the openings        155 which mostly are present on the fixed part in multiple        numbers, thereby reducing the risk of a faulty assembly; another        advantage is that the clamping plugs 154 will wiggle less as        they hang on the same basis and thus will have less tendency to        come loose by themselves;    -   The attachment system makes use of a common basis 159 with two        or more clamping plugs 154 formed thereon, wherein the basis 159        is made as a small plate; amongst others, this offers the        advantage that a proper application of the attachment element        mostly is facilitated.

The assembly and working of the attachment system 148 can simply bededuced from the above description and the drawings. It is clear thatthe attachment system 148 can also be applied for attaching otherfurniture fittings.

FIGS. 81 and 82 represent a variant, wherein the fixed part 187 and themovable part 189 are not connected by a hinge with a pin, but rather bymeans of a film hinge 193. Optionally, at the fixed part a pin 194 orpressure screw part can be present, which engages in an opening in thedoor. This can also be applied in the preceding embodiment.

FIGS. 83 and 84 represent another variant, viewed along both sidesthereof. The represented hinge attachment 186 is special in that itshows one or more of the following features, which, in the representedexample, all are combined, however, may also be present as such or inany lesser combination:

-   -   All component parts, or at least all wall parts thereof, can be        marketed in a substantially flat configuration, which allows        packaging them along with flat-pack furniture in a smooth        manner;    -   Two or more walls forming a corner part are coupled to each        other via hinges 195-196, preferably film hinges; in the        example, all three walls 190-191-192 are coupled together by        hinges, in this case, film hinges.

It is clear that the walls 190-191-192 then can be folded into a cornershape as in FIGS. 81 and 82 in order to then attach them to thecorresponding surfaces of the door, for example, by means of adhesiveconnections and/or in other manners. The opening 197 is optional andallows guiding an extra pin there through.

By means of FIGS. 85 to 104 , hereinafter some more rear wallconstructions according to the invention are described.

FIGS. 85 to 90 illustrate a number of alternatives to the embodiment ofFIGS. 3 and 4 . The particularity of the embodiments of these figuresconsists in that one or more spacers 198 are provided for keeping therear wall parts 9-10 at least initially at a distance X from each other,in order to allow providing one or more attachment pieces 44 herebetween, wherein these spacers 148 are different from the rear wallparts 9-10, in other words, contrary to the embodiment of FIG. 3 , donot form part of the rear wall parts themselves. Amongst others, thisoffers the advantage that, if desired, no particular recesses 59 have tobe provided in the edges of the rear wall parts, such that it ispossible to work with simple straight edges. In this manner, the rearwall parts 9-10 can be realized considerably simpler, as all edges canbe made exclusively by straight-lined cutting treatments, for example,sawing treatments. However, this does not exclude that according to anot-represented variant rear wall parts with non-straight edges, forexample, with recesses 59, still are combined with spacers not formingpart of the rear wall parts themselves.

In general, said spacers 198 preferably consist of protrusions which, inmounted condition, are situated between the rear wall parts 9-10. Inrear wall parts 9-10 which are mounted on top of each other, theprotrusions form supports which support the rear wall part 10respectively situated directly there above, and such at a distance Xabove the rear wall part 9 situated there below, in such a manner thatone or more attachment pieces, of which kind whatever, can also beprovided between the rear wall parts.

The protrusions can be provided at different locations, however,preferably they are situated at the sidewalls and/or partition walls ofthe furniture and/or at the rear edges of one or more shelves.

In the case of embodiments wherein the rear wall parts can be providedin the grooves 21-22 via passages 33-34, such protrusion can bepositioned at the height of such passage, such that a rear wall part canbe pushed into the respective grooves via the passages and over therespective protrusions, mostly by bending, after which this rear wallpart can be rested on the protrusions.

It is noted that such protrusions can also be applied exclusively forsupporting rear wall parts independently from each other in a piece offurniture, thus, without applying attachment pieces.

FIG. 85 represents a first practical embodiment, wherein a protrusion,in this case in the form of a plug 199, is provided in the groove 22,such at the height of the respective passage 34. It is clear that asimilar protrusion is provided on the other side of the piece offurniture. The rear wall parts 9-10 then can be pushed according toarrows A1 and A2 above and below the protrusions into the grooves, afterwhich the uppermost rear wall part 10 comes to rest on the protrusions,in this case the plugs 199, and a distance X is guaranteed between therear wall parts 9-10, said distance allowing, for example, thatattachment parts 44, as aforementioned, can be provided in an opening 47in a shelf. It is clear that the edges of the rear wall parts, whichedges are facing each other, then can have a simple straight-linedcontour.

In FIG. 86 , a variant is represented, wherein use is made ofprotrusions in the form of plugs 200 which are provided in the rear edgeof a shelf.

In FIG. 87 , a variant is represented wherein the protrusion is realizedon the rear edge of a shelf, and in this case is formed in one piecetherewith in the form of a cam-shaped protruding portion 201, such thatno separate parts are necessary. Such one-piece profile, which isprovided with a protrusion, can be realized such, for example, asexplained herein below by means of FIGS. 88 and 89 . Herein, first acontinuous tongue profile 202 is realized over the entire length of therear edge, as illustrated in FIG. 88 . Subsequently, at the height ofthe tongue profile 202, a groove profile 203 is realized, for example,is milled in, as illustrated in FIG. 89 , wherein the respective millingcutter just is drawn back somewhat on the location where the protrusionhas to be effected, whereby the tongue profile locally remains presentin the form of a local protrusion or, thus, portion 201, whereas thegroove profile 203 then forms the opening or groove 47 in which one ormore attachment pieces can be provided.

In FIG. 90 , a variant is represented, wherein the protrusion isrealized in a continuous manner in the form of a tongue 204, wherein therecesses above and below the tongue function as seats for the rear wallparts 9-10. In the tongue 204, an opening is formed, in this case in theform of a groove 47 in which attachment pieces 44 can be provided.Possibly, such protrusion can also be provided locally, whether or noton a plurality of locations.

In FIG. 91 , a particular embodiment is represented of an attachmentpiece 44 which as such combines various features. The attachment piece44 comprises an attachment part 45 with which it can be attached to thepiece of furniture, and a stop-forming part 49, which can cooperate withthe rear wall parts 9-10. In the example, the attachment portion isperformed as a clamping part, which can be pressed down in an opening47. The stop-forming part 49 is made as a flange with wings 50-51 andhas various functions. A first function consists in that the flangefunctions as a support part for the uppermost rear wall part 10. Asecond function consists in that the wings function as tensioningelements which, in one or more directions, exert tensioning forces onthe rear wall parts. In the represented example, these are lateraltensioning forces T1, which press down the rear wall parts 9-10 in theirremaining seats, as well as frontal tensioning forces T2, which pressdown the rear wall parts against the shelf 8. A third function consistsin that the attachment piece 44 possibly can be mounted beforehand andthat the flange allows to press down the rear wall parts 9-10 behind theedges of the wings by a frontal pressing-down movement M. Herein, theedges of the wings shortly will bend inward in order to subsequentlyelastically engage behind the edges 205-206 of the rear wall parts 9-10.

In FIGS. 92 to 94 , another particular embodiment of an attachment piece44 according to the invention is represented, which can be pressedsmoothly into the groove-shaped opening 47 by means of a turningmovement. The attachment piece 44 comprises an attachment portion 45 anda stop-forming part 49. The attachment portion 45 consists of apreferably semi-circular body 207, which, due to its relatively flatdesign, fits into the groove-shaped opening 47, wherein this body isprovided with curved ribs 208, which preferably are present on bothsides of the body 207 and, when being provided, tension against thewalls of the groove 47 and more or less cut therein. Due to the curvedshape of the ribs 208, automatically a rotation movement is induced whenthey are pressed on. As represented, the ribs 208 preferably are made ascutting ribs, thus, with a relatively sharp distal edge. It is alsopreferred that they systematically increase in height towards thestop-forming part. At the extremity 209 of the body 207 which isintended for being first inserted into the opening, preferably one ormore local clamping parts 210 are formed, which, when installing theattachment piece, provide for an initial clamping in order to more orless form a hinge point.

The working can simply be deduced from FIG. 94 and substantiallyconsists in that such attachment piece 44 first is pressed with theextremity 209 somewhat into the groove 47 and subsequently a force isexerted onto the exterior side of the stop-forming part 49, which causesthe body 207 to become fixed in the groove 47 by means of a turningmovement. The distance between the rear wall parts can also be chosensuch that the ribs 208 also cooperate with the edges of the rear wallparts, with the extra advantage that a higher rigidity of the piece offurniture is obtained in that the rear wall parts mutually can no longershift in lateral direction.

In FIGS. 95 to 97 , also a particular embodiment of a rear wall 2 isrepresented, wherein FIG. 97 at a larger scale illustrates the partindicated by F97 in FIG. 95 . Herein, the particularity consists in thatthe rear wall 2 is composed of a plurality of rear wall parts,preferably two separate rear wall parts 211-212, which can be fittedinto each other via edge profiles 213-214, more particularly can bepressed into each other and/or can be mutually pivoted into each other,while preferably being laterally taken up in seats 215-216. In certainapplications, this offers the advantage that such rear wall, afterinstalling the remaining parts of the piece of furniture, still can beprovided in the piece of furniture and can be removed therefrom as well.

The edge profiles preferably are made as a tongue 217 and a groove 218,with locking parts 219-220, which keep the rear wall parts together attheir edges.

Herein, the edge profiles can be configured such that they have to bepushed over a dead point while being joined together to form theintended rear wall, such that an automatic turning back is counteracted.

Further, means can be provided which determine the end position, such asa stop, for example, a plug 221 or alternatively a groove 222, forexample, in the bottom of the cupboard, into which the rear wall candrop in in the final condition.

In the example, the rear wall parts are forced into their flat conditionfrom the interior of the piece of furniture. This application can beuseful with kitchen cupboards, for example, with applications whereinthe distance Z is larger than usual, and the then created space isapplied for hiding cables behind the rear wall, wherein the rear wallthus can be provided after the cables are mounted, and it is alsopossible to remove the rear wall temporarily in the case of possiblerepairs.

In FIGS. 98 and 99 , another rear wall construction according to theinvention is represented, wherein the particularity consists in that therear wall 2, or at least a rear wall part thereof, is fixed by means ofpressing elements 223 which cooperate with openings 224 in the furnitureparts. This offers the advantage that the whole can be designed suchthat first a carcass can be built and afterwards the rear wall can bemounted therein.

Herein, the rear wall part preferably will be seated in a recessedportion 225. As more clearly represented in FIG. 99 , the pressingelements 223 can consist of press-on plugs, which are provided in therespective rear wall part through openings 226 and which engage in theopening or openings 224 by means of clamping portions 227, for example,by means of a clamping toothing. The openings 226 preferably consist ofbore holes, whereas the openings 227 preferably consist of grooves. Suchattachment can be applied along the entire circumference of a rear wallor rear wall part, or only along a portion thereof.

In FIGS. 100 to 104 , also a tensioning device 228 is represented, whichallows increasing the rigidity of a composed element, more particularlya piece of furniture, by making an additional connection between therear wall 2 and a constructional part in which the rear wall isprovided, in this case a sidewall 5.

Herein, FIG. 100 in perspective represents a view where such tensioningdevice 228, amongst others, can be provided. FIG. 101 represents thetensioning device as such. FIG. 102 represents a cross-section accordingto line CII-CII in FIG. 100 after the tensioning device 228 has beenprovided, however, is not yet fixed, whereas FIGS. 103-104 , for twodifferent positions, represent a cross-section according to lineCIII-CIII in FIG. 102 .

The tensioning device 228 consists of a basic body 229 with attachmentmeans 230 for providing the tensioning device 228 on a constructionalpart, in the example the sidewall 5, of the piece of furniture, andhaving an engagement system 231 which can cooperate with the rear wall2.

The attachment means 230 consist of at least two pins 232-233 with whichthe whole can be provided in openings 234-235 in the constructional part5. A first of these pins 232 is fixedly installed, whereas the other pin233 is made as an eccentric part which can be turned via a handle 234,wherein the eccentricity is chosen such that, when the handle is beingturned, the effective distance between the pins changes and a clampingis obtained in the openings, in this case in that the pins move towardseach other and will clamp towards each other against the intermediatematerial part of the piece of furniture. The engagement system 231 isformed by an eccentrically installed disk 235 which in the example alsocan be turned by means of the handle 234 and by turning engages in therear wall and/or tensions against it. According to not-representedvariants, the disk can also be replaced by another element, such as apin or the like, wherein this element can cooperate with the back by adisplacement.

According to the invention, such tensioning device can also be realizedwith other forms of attachment means 230 and of an engagement system231.

It is clear that different variants on all herein above-describedembodiments are possible without leaving the scope of the invention.
